No justification for rates

We have been paying for personal water use and the water system every time we receive a utility bill from the city of Davis all the years I have lived in Davis. When water meters were installed, we started paying for them also in every water bill.
Woodland has the same water system of wells, pumps, pipes, meters, etc. as Davis has, but Woodland is not imposing the complex water rate system on their residents as the city of Davis is doing and trying to justify.
I see no justification for the complex water rates Davis is instituting.
